UNITED STATES ECTOR F. MARCEAU, OF EAST HARTFORD, CONNECTICUT.

NK AGITATOR.

Application filed April 23, 1925.

To ZZ whom t may concern Be it known that I, EoTor. F. MARCEAU, a citizen of the United States, residing at East Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in lnk Agitators, of which the following is a specitication.

This invention relates to those devices which are adapted to be applied to printing presses for keeping the roll in the ink fountain supplied with the desired quantity of ink, of the class illustrated and described in Patent #1,379,359 issued to ine May 24, 1921.

The object of the present improven'ient is to simplify the construction and provide a cheap and efficient appliance which can be readily attached to the frames oit the coinmon forms of printing presses adjacent to the ink fountains, and which has nieans that will travel continuously back and forth and uniformly distribute thick ink in the re quired quantity to the desired area on the hiking roll that is mounted in the ink fountain, when the press is ruiming'.

ln the accompanying drawings Fig. 1 shows a plan of an ink distributing appliance which enibodies the invention, the ink -fountain and roll being well known by those employed in the art are not illustrated. Fig. 2 shows an elevation of the apparatus. Fig. 3 shows a vertical section on the plane indicated by the dotted line 3-3 on Fig. 2 looking in the direction of the arrows.

The appliance illustrated has a pair of clamp plates 1 that are designed to be litted on and fastened by screws 2 to the walls of the press with which the device is to be used. Attached to the front of the clamp plates are angular brackets 3 which support the ends of a pair ot' parallel guide rods L1. Free to rotate on a stud 5 on the front of one of the brackets is a wheel ti, which muy be'ja pulley or sprocket. ',lurning in the other bracket is an arbor i". Attached to the front end of this arbor is a wheel S, which may be a pulley or sprocket, and attached to the rear end of the arbor :is a bevel gear 9. Meshing with this gear is a bevel. gear 10 attached to the end of a shaft 11 that is rotatably supported by an extension 12 from the bracket. The outer end of the shaft has a pulley 13 that: may be belted to any convenient rotatable part of the Serial No. 25,399.

press. An endless belt or chain 111 passes around and connects the driving wheel 8 with the idler wheel 6. `When the pulley and shaft are rotated the gears drive the wheel 8 and cause the belt or chain to travel around the wheels in the direction indicated by the arrow 15. F ig. 2.

Loosely mounted so as to slide on the parallel guide rods that are supported by the brackets is a carriage 16, the upper and lower edges of which are grooved to tit the rods.V @n the front face of this carriage are studs 17 and 18, turning freely on the former of which is a pulley or sprocket wheel A19 and on the latter of which is a pulley or 'sprocket wheel 20. The wheel 19 is arranged to engage with the under side of the upper length of the belt or chain that passes around the wheels ti and 8, while the wheel 18 is arranged to engage with the up.

per side of the lower length of the belt or chain. Guide posts 21 are preferably attached to the carriage so as to hold the belt or chain Vin engagen'ient with the wheels 19 and 20. Projecting backward from the wheel 19 is a stud 22 and projecting backward from the wheel 2O is a stud 23.

Movable horizontally in the carriage back of the wheels 19 and 20 is a slide 24 which has a forwardly extending portion 25 that is adapted, depeiiding upon the position of the slide, to extend into the paths of revolu` tion of the studs 22 and Adj'iistably mounted on the guiding rods are stop pieces 26. These stops are clamped in the positions to which they are adjusted by thumb screws 2T. The ends of the slide 24- extend beyond the ends of the carriage and the projection 25 from the slide is of such a length that when it is in the path of one of the studs 22 or 23 the other stud is Ytree to revolve.

The parts are illustrated in such relation that the stud 22 is engaged by the exteiisiz'm 25 of the slide 24A. This prevents the wheel 19 from rotating. Under these conditions, as the wheel 19 is locked and cannot rotate the chain inovcs the carriage toward the left. During this movement the wheel 2t) rotates idly. direction until the slide 24e engages the stop 26 and the slide is pushed relatively to the carriage to the right. This action moves the slide extension 25 out of the path of the stud 22 and into the path of th@ stud 23,

The carriaoe travels Vin this I releasing the wheel 19 and locking the Wheel 2() against rotation. Then the carriage is moved by the chain to the right. until the end of the slide 24 engages the other stop 26 and is pushed back to the position illustrated in Fig. 2, and causes the travel of the earriafre to be reversed. The path of travel of t e carriage is determined by the location of the stops on the guiding rods. .fit the bach of the carriage is a bracket 2S to which, by a thumb screw 29 any suitable form of agitator blade 30, may be attached. Vith this construction the carriage is caused to travel back and forth continuously when the press is running so that the agitator will lreep the ink in the desired condition.

The invention claimed is l. An ink agitator comprising means for attaching the appliance to a printing press, guiding means supported by the attaching means, a carriage movable back and forth en the guiding means, said carriage being adapted to support an agitator blade, wheels mounted on the attaching means, an endless belt connecting said wheels, mechanism for rotating one ot said Wheels, Wheels rotatably mounted on the carriage, one of which is engaged by one length of the belt and the other ot Vwhich is engaged by the other length ot the belt, means movably mounted on the carriage and adapted to intermittently release one et said carriage wheels and lock the other ot said carriage Wheels, and stops adapted to engage and change the position o'l' said movable .means with relation to the carriage Wheels at the predetermined limits ot travel of the carriage.

An ink agitator comprising means tor attaching the appliance to a printing press, parallel guiding rods supiiorted by the attaching means, a carriage movable haelt and Ylorth on said rods, said carriage being adapted to support an agitator blade, Wheels mounted on the attaching means, an endless belt connecting said wheels, mechanism tor rotating one ot' said wheels, wheels rotatably mounted on the carriage, one et which is engaged by one length ot the belt and the other ol? which is engaged by the other length ot the belt, means movably mounted on the carriage and adapted to intermittently release one ot said carriage Wheels and lock the other ot said carriage Wheels, and stops adapted to engage and change the position of said movable means with relation to the carriage Wheels at the predetermined limits of travel of the carriage.
